[0028] (2) Disinfection of explants: choose grape hyacinth bulbs as explants, wash them with tap water for 1 hour, disinfect them with 1% 84...

Embodiment 2

[0035] Embodiment two: a kind of method adopting plant tissue culture grape hyacinth, comprises the following steps:

[0036] (1) Preparation of medium: MS medium was selected as the basic medium, and 2,4-D, IAA, NAA, 6-BA and IBA were used as regulated growth hormones to prepare five kinds of medium respectively: Medium A: MS+2 , 4-D1.0mg / L+6-BA 2.0mg / L, medium B: MS+NAA 1.0mg / L+6-BA 2.0mg / L, medium C: MS+IBA 1.0mg / L+6 -BA2.0mg / L, medium D: MS+IAA 1.0mg / L, medium E: MS+IBA1.0mg / L; medium A, B, C and D were supplemented with 30g / L sucrose and 5g / L agar, add 30g / L sucrose and 2g / L agar in medium E, adjust the pH to 6.0 with 2mol / L NaOH solution and HCL solution, and mix medium A, B, C, D and E Sterilize in a high-pressure steam sterilizer at 125°C for 20 minutes, and the pressure in the high-pressure steam sterilizer is 0.15MPa;

[0037] (2) explant disinfection: select the grape hyacinth bulb as the explant, after rinsing with tap water for 2h, disinfect it with 2% 84 disin...

Embodiment 3

[0044] Embodiment three: a kind of method adopting plant tissue culture grape hyacinth, comprises the following steps:

[0045] (1) Preparation of medium: MS medium was selected as the basic medium, and 2,4-D, IAA, NAA, 6-BA and IBA were used as regulated growth hormones to prepare five kinds of medium respectively: Medium A: MS+2 , 4-D0.6mg / L+6-BA 1.2mg / L, medium B: MS+NAA 0.6mg / L+6-BA 1.2mg / L, medium C: MS+IBA0.6mg / L+6 -BA 1.2mg / L, medium D: MS+IAA0.4mg / L, medium E: MS+IBA0.6mg / L; medium A, B, C and D were supplemented with 26g / L sucrose and 4.5 g / L agar, add 26g / L sucrose and 1.5g / L agar in medium E, adjust the pH to 5.9 with 1.5mol / L NaOH solution and HCL solution, and mix medium A, B, C, D and E are sterilized at 122°C for 16 minutes in a high-pressure steam sterilizer, and the pressure in the high-pressure steam sterilizer is 0.12MPa;

[0046] (2) Disinfection of explants: choose grape hyacinth bulbs as explants, wash them with tap water for 1.2 hours, disinfect them w...

Abstract

The invention relates to a method for culturing muscari botryoides mill with plant tissues, comprising the following steps of: (1) preparing culture mediums: the culture medium A prepared from MS, 2, 4-D and 6-BA; the culture medium B prepared from MS, NAA and 6-BA; the culture medium C prepared from MS,IBA and 6-BA; the culture medium D prepared from MS and IAA; and theculture medium E prepared from MS and IBA; (2) disinfecting an explant; (3) inoculating the explant on the culture medium A for inducing culture to obtain a callus; (4) proliferation culture: transferring the callus to the culture medium B for culturing; (5) differentiating adventitious bud: transferring the callus which is subjected to propagation culture to the culture medium C to obtain the differentiated adventitious bud; (6) rooting culture: transferring the adventitious bud to the culture medium D for culturing to obtain a tissue cultured seedling; (7) subculturing: transferring the rooted tissue cultured seedling to the culture medium E; and (8) seedling adaptation: transplanting the tissue cultured seedling in a nutrition cup and then transplanting into a greenhouse. The method provided by the invention solves the problem that, since the muscari botryoides mill has low breading rate and carries virus, the breed of muscari botryoides mill degrades seriously and bulbs wither, which is bad for the continuation and development of the quality.

Description

technical field [0001] The invention relates to a method for cultivating grape hyacinth, in particular to a method for cultivating grape hyacinth by using plant tissue, and belongs to the technical field of plant tissue culture. Background technique [0002] Grape hyacinth (Muscari botryoides Mill) is a genus of blue pot flowers in the family Liliaceae, also known as blue pot flowers, grape lilies, and grape narcissus. Grape hyacinth is a perennial herbaceous bulbous flower, the plant is short, the leaves are linear-lanceolate, clustered, 10-30cm long, 0.5-1.5cm wide, spikes, 1-3 branches drawn from the leaf clusters, upright cylindrical , flower stems 10-30cm high, with 20-40 flowers.
